View Full Version : My latest Homemade Longbow

I am going to show the steps in making this bow for my son. I am not an expert by any stretch. This will be a build along sort of thread but I must warn you that this will be slow going. I have many projects in the works with much stricter time lines than finishing this bow for my son so there will be periods of inactivity. Thats just real life.
This bow will be a reflex/deflex Long bow. It is a hybrid combination of a longbow and a recurve. Longbows are typically straight when unstrung and recurves are still curved even when unstrung. This bow will look sort of like a recurve while unstrung and like a longbows when strung.
Here is a pic I stole off the web to give you an idea of what I am going for.
http://i28.photobucket.com/albums/c239/212007154/josh%20bow/bowidea.jpg
The woods I am using for Josh's bow are the same ones I use to make knife handles. For the most part, they are South American hardwoods. The riser will be made from Bubinga, Bloodwood and good old American hard rock maple from a tree my Dad cut many years ago. Sort of a legacy piece of wood, cut by my Dad, Made into a bow by me and finally used by my son. I will also use some of the Maple in the limbs.
http://i28.photobucket.com/albums/c239/212007154/josh%20bow/joshbow1.jpg
this is the order in which I will stack the layers.
http://i28.photobucket.com/albums/c239/212007154/josh%20bow/joshbow2.jpg
Most S.A. hardwoods have oils in them that make gluing difficult, so I use acetone to clean and degrease. Blood wood and purple hear are some of the oiliest. You can see the orange oil in the basin of the sink. It took a long time to clean that sink. I should have sprayed it with pam first. :oops:
http://i28.photobucket.com/albums/c239/212007154/josh%20bow/joshbow3.jpg
Once cleaned, I used a hacksaw blade as a scrapper to rough up all the gluing surfaces. Epoxy does not like smooth surfaces.
http://i28.photobucket.com/albums/c239/212007154/josh%20bow/joshbow4.jpg
The glue I am using can be purchased at a number of bow building web sites. This is a two part epoxy that gets stronger if cured under a heated condition. This is important because if you leave the bow in a hot car on a sunny day, The glue had better have been cured at a high temp to keep the bow from de-laminating.
http://i28.photobucket.com/albums/c239/212007154/josh%20bow/joshbow5.jpg
It mixes like any other epoxy.
http://i28.photobucket.com/albums/c239/212007154/josh%20bow/joshbow6.jpg
Make sure to cover your work surfaces with wax paper or plastic wrap. It is hard to clean up any spills. Then simply butter both sides of the surfaces to make sure you have no dry spots that will later separate.
http://i28.photobucket.com/albums/c239/212007154/josh%20bow/joshbow7.jpg
I use spring clamps because C-clams will get loose during the heating process when the glue oozes out. (trust me, there is a lot of oozing) :( Spring clamps keep a constant pressure at all times.
http://i28.photobucket.com/albums/c239/212007154/josh%20bow/joshbow8.jpg
I then take the riser and put it in a preheated oven. Bake for 8 hours at 180F until a nice golden brown and serve with a scoop of vanilla ice cream . ::)
When it comes time to glue up the bow itself, I will build an oven box that is 6 feet long as the bow will not fit in the oven. I will heat this box with 100 watt light bulbs.
Fast forward 8 hours and a few more hours for a slow cool down period and the riser is all glued up. The rubber tips of the clamps need to be pried from the glue.
http://i28.photobucket.com/albums/c239/212007154/josh%20bow/joshbow92.jpg
Next, I ran the block through my table saw to square it up and remove the excess glue.
http://i28.photobucket.com/albums/c239/212007154/josh%20bow/joshbow93.jpg
http://i28.photobucket.com/albums/c239/212007154/josh%20bow/joshbow94.jpg
Then I drew the riser pattern on the wood and cut it out with a band saw and sanded the fade outs on a drum sander.
http://i28.photobucket.com/albums/c239/212007154/josh%20bow/joshbow95.jpg
http://i28.photobucket.com/albums/c239/212007154/josh%20bow/joshbow96.jpg
This glue is a flexible epoxy. Normal hardware store epoxy would crack and break if bent like this.
http://i28.photobucket.com/albums/c239/212007154/josh%20bow/joshbow97.jpg
Make sure to use only enough glue for the job at hand. A little goes a long way.
http://i28.photobucket.com/albums/c239/212007154/josh%20bow/joshbow98.jpg
I now need to make the form that I will use to glue the bow on and I need to make the heat box. Like I said, this is going to be a slow moving project. I will post more progress as I get a chance to work on it.

Before I can go any farther with Josh's bow, I need to build the form that the bow will be glued together on. There are a lot of ways to go about this and forms can be made many ways but I chose a way that seemed easy to me.
I bought a nice straight 2 x 10 and traced the form that I came up with onto the wood.
http://i28.photobucket.com/albums/c239/212007154/josh%20bow/joshbow1111.jpg
Then cut it out with a jig saw.
http://i28.photobucket.com/albums/c239/212007154/josh%20bow/joshbow1112.jpg
http://i28.photobucket.com/albums/c239/212007154/josh%20bow/joshbow1113.jpg
I then went over the entire length of the curve with a square to make sure there were no twists in the form. Any irregularities were taken out by sanding.
In order to keep the form straight over time and in the heat of the oven box, I screwed a few 2x4's along both sides. They will also act as feet to keep the form from tipping over. Next, I covered the entire curve with a piece of 1/8th inch thick by 1 1/2 wide aluminum strip. This will make the the curve a much better surface to build the laminations on and it will be more repeatable should I want to build more bows from this form. This form will build bows up to 70 inches in length. This bow will be a 66 inch model.
http://i28.photobucket.com/albums/c239/212007154/josh%20bow/joshbow1114.jpg
http://i28.photobucket.com/albums/c239/212007154/josh%20bow/joshbow1115.jpg
I spent some time making the clamp holes in the form. When I assemble the bow, I plan to use spring clamps to compress all the layers of wood, fiberglass and epoxy together.
I drilled big round holes and then used a jig saw to square up the side of the hole closest to the top surface. This will give the clamps a little more room.
http://i28.photobucket.com/albums/c239/212007154/josh%20bow/joshbow116.jpg
http://i28.photobucket.com/albums/c239/212007154/josh%20bow/joshbow117.jpg
I will use one clamp on each side of the limb. Like this.
http://i28.photobucket.com/albums/c239/212007154/josh%20bow/joshbow118.jpg
I also got a package in the mail today from Old Master Crafter of Waukegan, IL. I ordered the wood laminations a few days ago and these things showed up a lot faster than I was told they would. (Great Service) It does not look like much for about $60 but what it is, is 6 taper ground action wood strips that are .065" thin on one end that taper at .001" per inch of length. The strips are 36 inches long and 1 1/2 inches wide. they came protected by two nice looking strips of Zebra wood. I will use them for knife handles at a later date.
http://i28.photobucket.com/albums/c239/212007154/josh%20bow/joshbow119.jpg
http://i28.photobucket.com/albums/c239/212007154/josh%20bow/joshbow120.jpg
I placed the thick end of one piece next to the thin end of another so you can see the taper.
http://i28.photobucket.com/albums/c239/212007154/josh%20bow/joshbow121.jpg
Each limb will get three of these tapers and one strip of parallel thickness Hard rock Maple that is from the piece of wood my Father cut so many years ago. This is the same piece of wood that I used in the riser.
On the front and back of each limb will be a thin layer of Kingwood and then clear fiberglass. All of this will be assembled with the same epoxy I used to make the riser but first I need to assemble an oven box.

I built the oven box for the bow form. I will spare you the details since it's just a box made from scrap plywood that was left over from another project. I will say that It is 12 inches high and 22 inches wide and 74 inches long. By removing 6 screws at each end of the box, I can reduce the box to four individual panels for easy storage.
You will also notice that the box has neither a top or bottom. The reason for not having a bottom is so that I can bring the box to the form that will be covered in oozing epoxy and many clamps (creating a challenge to move) I would rather bring the box to the form.
http://i28.photobucket.com/albums/c239/212007154/josh%20bow/joshbow122.jpg
With the box complete, I assembled the heat source that I will use to raise the inside temp of the box to 160F. A trip to the Home Depot for the supplies ran me about $30.
http://i28.photobucket.com/albums/c239/212007154/josh%20bow/joshbow123.jpg
The first step was to get rid of those pesky warning labels. Nobody reads them any way. The extension cord company knows I am not going to read the label in English so why would they expect me to read it in Spanish? I hope the extension cord labels are not like mattress labels. I would have to spend time behind bars for removing them.
http://i28.photobucket.com/albums/c239/212007154/josh%20bow/joshbow124.jpg
Once I cut the extension cord into bits, I wired the light bulb bases together in series so that one plug would power them all.
http://i28.photobucket.com/albums/c239/212007154/josh%20bow/joshbow125.jpg
A quick test revealed that I had had paid attention in shop class.
http://i28.photobucket.com/albums/c239/212007154/josh%20bow/joshbow126.jpg
I placed the form between the two light bulb boards and brought the box to the form. My Son will need to help with this part as the box is a bit long to handle alone. Everything fits nicely.
http://i28.photobucket.com/albums/c239/212007154/josh%20bow/joshbow127.jpg
The cover of the box will be an old closet door from our last house. It is hollow so it is light enough to move around and it was free.
http://i28.photobucket.com/albums/c239/212007154/josh%20bow/joshbow128.jpg
I drilled a hole in the door and inserted the probe of a thermometer. This way, I can keep tabs on the temp inside the box without opening it and letting the heat escape. My wife won't be cooking a turkey for a few months anyway.
http://i28.photobucket.com/albums/c239/212007154/josh%20bow/joshbow129.jpg
After two hours with the bulbs on, the temp never got above 135F. I will replace the 100 watt bulbs with 150 watt bulbs and add two additional bulbs to the boards
http://i28.photobucket.com/albums/c239/212007154/josh%20bow/joshbow130.jpg[/quote]
The next test will include covering the oven box with a canvas to trap the heat better. I think 2 extra bulbs should do the trick.
The next step will be to make a test bow out of scrap material so I get the feel for the assembly process and so that I can check the glued up trial piece for any warps that I will be able to correct before wrecking a bunch of expensive woods and fiberglass. It is a piece of mind exercise.

In order to evaluate the bow form, I built a mock up. I bought a pine, 2 x 6 and cut it into strips that were .065 thick.
http://i28.photobucket.com/albums/c239/212007154/josh%20bow/joshbow131.jpg
Before gluing the strips together, I protected the form with two layers of tape. It will be easier to remove and replace the tape then it will be to try and chip away any excess glue from the form.
http://i28.photobucket.com/albums/c239/212007154/josh%20bow/joshbow132.jpg
Next, I covered the surfaces of the form with plastic wrap to keep it clean.
http://i28.photobucket.com/albums/c239/212007154/josh%20bow/joshbow133.jpg
I used yellow wood glue for the mock up. It did not require the oven box. Once all the layers were covered in glue, I used clamps and strips of rubber inner tube to compress the layers.
http://i28.photobucket.com/albums/c239/212007154/josh%20bow/joshbow134.jpg
In the center section (where the riser will be) I added a few extra strips.
http://i28.photobucket.com/albums/c239/212007154/josh%20bow/joshbow135.jpg
After 24 hours, I removed the clamps and the plastic wrap. There was no "Spring back" or relaxing of the wood strips. I then took the mock up and reversed it on the form to see if it was symmetrical and it fit the form equally in either orientation.
http://i28.photobucket.com/albums/c239/212007154/josh%20bow/joshbow136.jpg
I checked for twists in the limbs and found none.
http://i28.photobucket.com/albums/c239/212007154/josh%20bow/joshbow137.jpg
http://i28.photobucket.com/albums/c239/212007154/josh%20bow/joshbow138.jpg
I then placed the riser against my chest and grabbed both limb tips and began to flex the bow. Since I did not have any fade outs and the ridged glue does not like to flex (and the pine had many knots) both limbs broke
http://i28.photobucket.com/albums/c239/212007154/josh%20bow/joshbow139.jpg
This allowed me to nest the limbs and look for any twists or differences between the two. Everything looked good.
http://i28.photobucket.com/albums/c239/212007154/josh%20bow/joshbow141.jpg
I think all is ready to assemble Josh's bow. Since I will want to baby sit the oven box for the 8 hours that it will cook, It's going to have to wait until I have a free weekend.

Based on some tests I decided to insulated the inside of the oven box. I bought a roll of insulation that is made from a double layer of bubble wrap with heavy duty foil on both faces. It is just under a 1/4 inch thick and lightweight.
http://i28.photobucket.com/albums/c239/212007154/josh%20bow/joshbow142.jpg
I used a staple gun to attach it to the inside walls of the box and to the under side of the box cover.
http://i28.photobucket.com/albums/c239/212007154/josh%20bow/joshbow146.jpg
I then added two additional light bulb bases to the boards that I had made up earlier. I used 100 watt bulbs in the center two bases so now I have (4) 150 watt bulbs and (2) 100 watt bulbs.
http://i28.photobucket.com/albums/c239/212007154/josh%20bow/joshbow145.jpg
After one hours, the temp had risen to my goal temp of 160F. I felt the outside of the box in several locations and could not feel any heat escaping through the walls or lid.
http://i28.photobucket.com/albums/c239/212007154/josh%20bow/joshbow143.jpg
After 2 hours, the temp had risen above my goal but I consider this a good thing since I will now be able to crack the lid a bit or perhaps unscrew one bulb to control the temp.
http://i28.photobucket.com/albums/c239/212007154/josh%20bow/joshbow144.jpg
The oven box is finished and ready for the big day.
http://i28.photobucket.com/albums/c239/212007154/josh%20bow/joshbow147.jpg
I did a dry run of the bow build and found something I never thought through (Which is the point of a dry run)
http://i28.photobucket.com/albums/c239/212007154/josh%20bow/joshbow154.jpg
While the riser fits great on the empty form, adding the strip of fiberglass backing, four tapered laminations and the fiberglass face caused the fade-outs to lit poorly. I did not factor in the tapering of the laminations as they work away from the center of the riser. I discovered a gap at the fade-out area. I felt this gap was larger than it should be and do not want a large amount of epoxy at this hinge point. I might just be over cautious but I want a better fit and a consistent glue line. The dark black area near the thinest part of the riser is what I am worried about.
http://i28.photobucket.com/albums/c239/212007154/josh%20bow/joshbow156.jpg
I sanded down the riser until it fit better.
http://i28.photobucket.com/albums/c239/212007154/josh%20bow/joshbow155.jpg
I also made some tillering attachments that will slide on the end of the un-shaped limbs before I taper the sides and make the string groves. they are made from 4large washers that I epoxied together and cut notches in

So, enough waiting already. Time to glue this bow up. I laid out everything I needed since the dry run a few days ago. Then I put both quart containers of the epoxy in a basin of hot water to warm them up a bit.
http://i28.photobucket.com/albums/c239/212007154/josh%20bow/joshbow157.jpg
Next, I cleaned all the wood and glass surfaces and laid them in the order in which I would glue them.
http://i28.photobucket.com/albums/c239/212007154/josh%20bow/joshbow158.jpg
1. is .050 clear glass
2. is .020 kingwood vernier
3. is .090 thick hard maple taper (two pieces glued together to make one long piece)
4 and 5. is .065 thick hard maple taper (two pieces glued together to make one long piece)
6. is a piece of hard maple .060 parallel from the piece of wood my Dad cut. (two pieces glued together to make one long piece)
7. is .020 kingwood vernier
8. is .050 clear glass
Missing from the picture is the riser.
Fast forward to a completed glue up with the warmed epoxy. Due to the mess and the fact that I was working alone, I did not slip out of my sticky rubber gloves to take pictures along the way. What a slippery mess to work with. I used a combination of spring clamps and rubber inner tube strips to compress all the layers. I had more C-clamps at the center (on the riser) but I took them off once I realized that they stuck up higher than the sides of the box and the cover would not lay flat. So much for a complete dry run. I should have tried the lid of the box also. Oh well. live and learn.
http://i28.photobucket.com/albums/c239/212007154/josh%20bow/joshbow160.jpg
Here is a close up of all the layers and all the extra glue that oozed out. I also learned that I used too much glue. I think I could have built two bows with what came out from between the seams. Once again. Live and learn.
http://i28.photobucket.com/albums/c239/212007154/josh%20bow/joshbow161.jpg
Here is the oven box doing it's job of keeping the bow at around 160F. I will unplug it before I go to bed and let it slowly cool down over night.
http://i28.photobucket.com/albums/c239/212007154/josh%20bow/joshbow162.jpg
It was a day of ups and downs on the bow project. It took a solid hour to free the bow from the form. Removing the spring clamps was easy, The epoxy covered strips of inner tube proved to be a bit tougher. The form cleaned up easy because of all the tape I used to protect it.
http://i28.photobucket.com/albums/c239/212007154/josh%20bow/joshbow163.jpg
The bow was a little tougher. The extra epoxy was everywhere and held bits of the inner tube captive.
http://i28.photobucket.com/albums/c239/212007154/josh%20bow/joshbow164.jpg
To save on a mess in the shop (and because it was a nice day) I took the bow out to the back patio behind my shop. The breeze would blow all that nasty fiberglass dust away.
http://i28.photobucket.com/albums/c239/212007154/josh%20bow/joshbow165.jpg
I learned that I need to place a layer of plastic wrap between the last layer of glass and the aluminum pressure strip. I didn't do that with this bow and needed to sand away the excess epoxy to free it from the bow. This also gave me my first look at the glue lines between the layers of wood.
http://i28.photobucket.com/albums/c239/212007154/josh%20bow/joshbow166.jpg
after sanding both sides I could pry away the aluminum pressure strip.
http://i28.photobucket.com/albums/c239/212007154/josh%20bow/joshbow167.jpg
Then I just had to peel away the tape to see how the Kingwood looked under the clear glass.
http://i28.photobucket.com/albums/c239/212007154/josh%20bow/joshbow168.jpg
And the other limb.
http://i28.photobucket.com/albums/c239/212007154/josh%20bow/joshbow169.jpg
and finally the back of the bow. Everything looked good.

Then I worked on the riser. there was a lot of epoxy to remove.
http://i28.photobucket.com/albums/c239/212007154/josh%20bow/joshbow171.jpg
The risers looks good and so do the skive cuts that joined the strips of maple
http://i28.photobucket.com/albums/c239/212007154/josh%20bow/joshbow173.jpg
http://i28.photobucket.com/albums/c239/212007154/josh%20bow/joshbow172.jpg
I then made a line on each end of the limbs that was 34 niches from the center point of the bow. (68 inches overall length) I used a fine tooth hacksaw to cut the ends off.
http://i28.photobucket.com/albums/c239/212007154/josh%20bow/joshbow174.jpg
http://i28.photobucket.com/albums/c239/212007154/josh%20bow/joshbow175.jpg
Both ends measured the same thickness.
http://i28.photobucket.com/albums/c239/212007154/josh%20bow/joshbow176.jpg
Then I used the washers to string the bow before I cut the string grooves.
http://i28.photobucket.com/albums/c239/212007154/josh%20bow/joshbow177.jpg
Here is is strung but with a bow string that is too long so the brace height is only about 5 inches. I used the string from my longbow. It is the only string I have for that bow. (that is an important point that will be realized a bit later.
http://i28.photobucket.com/albums/c239/212007154/josh%20bow/joshbow180.jpg
To check for limb twist, I wanted to look at more than just saw cuts at the ends of each limb so I took a carbon fiber shaft and taped it in place on each limb. I made sure they were at 90 degrees to the limb.
http://i28.photobucket.com/albums/c239/212007154/josh%20bow/joshbow178.jpg
With the washers in the measured center of the limbs, there looks to be no twist in the limbs.
http://i28.photobucket.com/albums/c239/212007154/josh%20bow/joshbow179.jpg
I marked the centerline of the bow along the entire length and used a strip of wood to mark a straight line for the limb taper toward the string nocks.
http://i28.photobucket.com/albums/c239/212007154/josh%20bow/joshbow181.jpg
http://i28.photobucket.com/albums/c239/212007154/josh%20bow/joshbow182.jpg
Just as I was marking the last line on the other limb, all hell broke loose, Something whacked me in the finger and the bow jumped up off the table. When I figured out what it was, I had to search high and low for both washers. The bow string (my only string for my bow) had broke. My guess is that I left too sharp an edge on the inside of the groove and it cut through the string. Now I have no string for either bow. Time to scramble and locate a 64 inch string for my bow and a 63 inch string for the new bow.

If there is such a thing as a good time for a string to break, I guess I am lucky. I have a lot of work to do before I need a string again.
I used my belt sander with a 50 grit belt to grind down the limbs to the lines I scribed. My lovely bride got a picture of me at work.
http://i28.photobucket.com/albums/c239/212007154/josh%20bow/joshbow184.jpg
http://i28.photobucket.com/albums/c239/212007154/josh%20bow/joshbow185.jpg
Next, I marked the location of the string grooves in the ends of the limbs.
http://i28.photobucket.com/albums/c239/212007154/josh%20bow/joshbow186.jpg
Using a chainsaw file I made the beginnings of the string grooves. This will help me locate the tip overlays. when they are installed, I can finish the grooves.
http://i28.photobucket.com/albums/c239/212007154/josh%20bow/joshbow188.jpg
http://i28.photobucket.com/albums/c239/212007154/josh%20bow/joshbow187.jpg
For the overlays, I want to use Bloodwood and antler. The Bloodwood will match the accent strip in the riser and the antler is just something I wanted to try. I had a section of antler left over from a knife handle I made. I will use the longest tine as it has no pithy core. It is solid all the way through.
http://i28.photobucket.com/albums/c239/212007154/josh%20bow/joshbow189.jpg
Using the belt sander, I created a flat spot on the antler that will run against the rip fence of my table saw. I am using a carbide tipped finish blade so I get less chipping and a smooth cut.

http://i28.photobucket.com/albums/c239/212007154/josh%20bow/joshbow191.jpg
I made the strips about an 1/8th of an inch thick.
http://i28.photobucket.com/albums/c239/212007154/josh%20bow/joshbow192.jpg
In order to get the best adhesion with the epoxy, I needed to rough up the shiny surface of the clear glass. I used a hacksaw blade as a scraper. I did the same to the bloodwood and the antler.
http://i28.photobucket.com/albums/c239/212007154/josh%20bow/joshbow193.jpg
I used the same epoxy, I used for the rest of the bow build.

http://i28.photobucket.com/albums/c239/212007154/josh%20bow/joshbow195.jpg
I used only one bulb under each tip and some of the left over insulation from the hot box. Not much I can do except make the tillering tree.

With the antler and Bloodwood overlays glued in place. I began shaping the tips. I still have the very first fiberglass longbow I ever owned as a kid. It is a 25 pound bow and I wanted to make the tips of the new bow look something like my old bow.
http://i28.photobucket.com/albums/c239/212007154/josh%20bow/tip01.jpg
http://i28.photobucket.com/albums/c239/212007154/josh%20bow/tip02.jpg
I sanded all the edges flush and continued the string grooves I had already started.
http://i28.photobucket.com/albums/c239/212007154/josh%20bow/tip1.jpg
The rest really needs no explanation.

The groove has to have enough room so the string does not kink at full draw. I used the good end of the broken string and approximated the string angle.

It's a slow process but I think it gives the limb tips a very pleasing look.

After a short delay, I did get a replacement string from a very kind young man on a traditional archery site. He sent not one but two strings for Josh's bow. I offered to pay him and he would hear nothing of it. Trad folks are really good people.
He even matched the colors of the riser.
http://i28.photobucket.com/albums/c239/212007154/josh%20bow/joshstring.jpg
Before I could use the new string, I needed to build a tillering tree to check the limbs for even bending. I had a section of treated 2x4 up in the rafters of my garage for a few years so I knew it was good and dry. I drilled a series of 3/4" diameter holes at a 15 degree angle in the edge of the 2x4. The holes are 2 1/2 inches deep. In those holes, I glued short sections of 3/4 inch wooden dowels. I then sanded them to round off any sharp edges.
http://i28.photobucket.com/albums/c239/212007154/josh%20bow/tree1.jpg
And marked off the distances along the side.
http://i28.photobucket.com/albums/c239/212007154/josh%20bow/tree2.jpg
This is the bow holding end of the tree. I use a piece of leather to protect the riser when I clamp the bow in place.
http://i28.photobucket.com/albums/c239/212007154/josh%20bow/tree3.jpg
I attached a plywood base so it would stand by itself.
http://i28.photobucket.com/albums/c239/212007154/josh%20bow/tree4.jpg
With the string grooves filed and the tillering tree finished, I strung the bow for the first time. and drew it back. It was a good feeling. I then put it in the tree and drew the bow to a few different lengths to see if the limbs were flexing equally. Here are the pics.
http://i28.photobucket.com/albums/c239/212007154/josh%20bow/tree5.jpg
http://i28.photobucket.com/albums/c239/212007154/josh%20bow/tree6.jpg
http://i28.photobucket.com/albums/c239/212007154/josh%20bow/tree7.jpg
I can see some differences in the flex of the limbs. I will sand away certain areas to make the limbs act the same.
Lessons learned. I could have left out every other wooden peg. I really don't need one at every inch.

I then needed to cut out the sight window and shape the grip. I drew the window onto the tape on both the back and belly of the bow. The window will be 1/8th inch less than center.
http://i28.photobucket.com/albums/c239/212007154/josh%20bow/riser1.jpg
I used a hand saw and chisel to remove the wood.
http://i28.photobucket.com/albums/c239/212007154/josh%20bow/riser2.jpg
And then sanded it to the lines.
http://i28.photobucket.com/albums/c239/212007154/josh%20bow/riser3.jpg
I put a crown on the shelf.
http://i28.photobucket.com/albums/c239/212007154/josh%20bow/riser4.jpg
To shape the grip I used a wood rasp and sanding blocks
http://i28.photobucket.com/albums/c239/212007154/josh%20bow/riser5.jpg
http://i28.photobucket.com/albums/c239/212007154/josh%20bow/riser6.jpg
It still is a bit thick and will need to be slimmed down a bit.

After stringing the bow and having Josh draw it a few times, I asked him how the grip felt. He didn't like the bump in the center of his palm so I sanded it down a bit more and did all the finish sanding of the rest of the grip. While I was hand sanding, I looked up to see 3 young gals heading up the driveway to visit. I stopped sanding and grabbed the camera.
http://i28.photobucket.com/albums/c239/212007154/josh%20bow/does.jpg
They didn't hang around long after I told them what I was making. With the sanding done (320 grit) I masked off the riser leaving the bloodwood exposed. I cleaned it with denatured alcohol in preparation for sealing the oily bloodwood with super glue.
http://i28.photobucket.com/albums/c239/212007154/josh%20bow/grip1.jpg
I squeezed a line of glue on the wood and worked it in with my index finger using a circular motion and made sure not to stop long enough to become fused to the bow.
http://i28.photobucket.com/albums/c239/212007154/josh%20bow/grip2.jpg
The Super glue gives a nice shiny acrylic finish and seals and files the pores.
http://i28.photobucket.com/albums/c239/212007154/josh%20bow/grip3.jpg
After a 20 min. dry time, I peeled the tape and used 320 and the 400 grit sandpaper (including the glass) to take off the shine and smooth out the glue. The bloodwood is now sealed and now will accept the finish and dry at the same rate as the rest of the woods in the riser.

I decided to add a medal to the bow's riser so I used a hat/lapel pin that I got at the last Wisconsin Bowhunter's Annual convention. Being that I am a Director for the WBH, I though it would be a nice touch. This bow will come with a Junior membership to the WBH.
I drilled a shallow hole for the medal so that it would sit below the surface of the riser.
http://i28.photobucket.com/albums/c239/212007154/josh%20bow/medal2.jpg
It was a good fit.
http://i28.photobucket.com/albums/c239/212007154/josh%20bow/medal3.jpg
I then masked off the riser and cut away the tape covering the hole. I used two layers of tape so that when I used a putty knife to level the epoxy, It would sit just higher than the riser and allow me material to sand away to make flush.
http://i28.photobucket.com/albums/c239/212007154/josh%20bow/medal4.jpg
When the epoxy cured, I sanded it so the epoxy was level with the wood.
http://i28.photobucket.com/albums/c239/212007154/josh%20bow/medal5.jpg
http://i28.photobucket.com/albums/c239/212007154/josh%20bow/medal6.jpg
I kept on sanding until I had the whole bow smooth with 320 grit sandpaper.
http://i28.photobucket.com/albums/c239/212007154/josh%20bow/finish1.jpg
I then cleaned the bow with a tack rag and then wiped it down with denatured alcohol. I masked off the glass because I want to finish the riser with tung oil.
http://i28.photobucket.com/albums/c239/212007154/josh%20bow/finish2.jpg
I applied the Tung oil using the same "Brush" I used to apply the super glue to the bloodwood.
http://i28.photobucket.com/albums/c239/212007154/josh%20bow/finish3.jpg
I rubbed in a healthy dose of the tung oil and after it cures, I will give it two more coats. I will then use 400 grit and steel wool to smooth out any lines and give it two more coats.

08-11-2008, 09:44 AM
I had a lot of time in between coats of Tung oil so I started making some of the accessories Josh will need for the bow. The first thing he needs is a bow stringer.
I took an old bungee cord that I had removed the hooks from because I needed them for some other project and I cut off one end.
http://i28.photobucket.com/albums/c239/212007154/josh%20bow/stringer1.jpg
Then I trimmed off one side to create a flat surface. The flat is the surface that will contact the bow limb when being used. It took two cuts to get it where I wanted it.
http://i28.photobucket.com/albums/c239/212007154/josh%20bow/stringer2.jpg
The other end of the stringer will slip over the limb. This part, I made out of a piece of scrap leather.
http://i28.photobucket.com/albums/c239/212007154/josh%20bow/stringer3.jpg
I folded it in two and punched the stitching holes
http://i28.photobucket.com/albums/c239/212007154/josh%20bow/stringer4.jpg
Then sewed it using white, braided, waxed line.
http://i28.photobucket.com/albums/c239/212007154/josh%20bow/stringer5.jpg
Then I added a grommet for the rope to attach to.
http://i28.photobucket.com/albums/c239/212007154/josh%20bow/stringer6.jpg
Both ends were then connected using a strong nylon rope.
http://i28.photobucket.com/albums/c239/212007154/josh%20bow/stringer7.jpg
http://i28.photobucket.com/albums/c239/212007154/josh%20bow/stringer8.jpg
To use the string, On end is slipped over the lower limb tip.
http://i28.photobucket.com/albums/c239/212007154/josh%20bow/stringer9.jpg
And the rubber end is placed on the upper side of the other limb. The knot is tied far away from the rubber end to allow for clearance for the bow string to pass through.
http://i28.photobucket.com/albums/c239/212007154/josh%20bow/stringer91.jpg
I had Josh try it out on my old longbow since the Tung oil was still wet on his. One hand lifts the bow and the other hand slides the loop of the bow string into the string groove on the limb tip.
http://i28.photobucket.com/albums/c239/212007154/josh%20bow/stringer92.jpg
With the string finished, I moved on to a limb tip protector so that nice white antler limb tip won't become damaged when he sets the tip in the dirt.
I started with two thin pieces of suede leather and stitched them together to make a nice tight fit over the limb tip. I then cut a long slot in the back side for the bow string to pass through.
http://i28.photobucket.com/albums/c239/212007154/josh%20bow/protect1.jpg
It is a tight fit and that will keep it from falling off.
http://i28.photobucket.com/albums/c239/212007154/josh%20bow/protect2.jpg
I then trimmed away the extra leather around the outside and tried it with the bow string in place.
http://i28.photobucket.com/albums/c239/212007154/josh%20bow/protect3.jpg
http://i28.photobucket.com/albums/c239/212007154/josh%20bow/protect4.jpg
I still need to make a string keeper, an arm guard, a finger tab and a case for the bow as well as a set of arrows.
Rancid Crabtree
08-11-2008, 09:47 AM
I also needed to make Josh an arm guard and a finger tab to go with the new bow.
I used 5 Oz. tooling leather for the face and 4 Oz. Buffalo for the backer.
http://i28.photobucket.com/albums/c239/212007154/josh%20bow/bracer2.jpg
http://i28.photobucket.com/albums/c239/212007154/josh%20bow/bracer3.jpg
I added a little tooling with his initials.
http://i28.photobucket.com/albums/c239/212007154/josh%20bow/bracer4.jpg
And made some antler buttons.
http://i28.photobucket.com/albums/c239/212007154/josh%20bow/bracer5.jpg
I used a dark red/brown stain and attached elastic/bungee material to hold in in place,
http://i28.photobucket.com/albums/c239/212007154/josh%20bow/armguard2.jpg
http://i28.photobucket.com/albums/c239/212007154/josh%20bow/armguard3.jpg

http://i28.photobucket.com/albums/c239/212007154/josh%20bow/armguard5.jpg
For the finger tab, I traced the shape of my homemade finger tab for Josh's and cut out 3 of them from some medium thickness scrap leather.
http://i28.photobucket.com/albums/c239/212007154/josh%20bow/tab1.jpg
I then stacked the 3 and used brass rivets to hold them together.

08-11-2008, 09:49 AM
I then began to focus on the arrows for Josh's new bow. I bought Gold Tip Traditionals because of the wood grain look.
http://i28.photobucket.com/albums/c239/212007154/josh%20bow/josharrows1.jpg
After capping the back 9 inches of the shafts with white lacquer, I started cresting the shafts using a color scheme that resembles the riser. I will write Josh's name on all the shafts.
http://i28.photobucket.com/albums/c239/212007154/josh%20bow/josharrows2.jpg
http://i28.photobucket.com/albums/c239/212007154/josh%20bow/josharrow4.jpg
The fletching will be 4 1/2 inch long LW barred turkey feathers. Since nobody sells 4 1/2 feathers, I bought 5 inch parabolic cut and converted them to 4 1/2 shield cut.
http://i28.photobucket.com/albums/c239/212007154/josh%20bow/josharrows6.jpg
Now the fletching begins.
http://i28.photobucket.com/albums/c239/212007154/josh%20bow/josharrows5.jpg
One down, 11 more to go.
http://i28.photobucket.com/albums/c239/212007154/josh%20bow/josharrow7.jpg
While waiting for the fletches to dry, I made the rug rest and strike plate for the bow.
For the strike plate, I used 2-3 Oz. leather and for the rug, I used the fuzzy side of some adhesive backed Velcro strip I had laying around.
http://i28.photobucket.com/albums/c239/212007154/josh%20bow/rest1.jpg
The leather was from some scrap I had so I needed to add some double sided tape to make it stay on the riser.

08-11-2008, 09:51 AM
With the finish on the bow all set and hard, I was able to to the task of making the leather grip. The finished wood was very slick and needed some texture. I started with a piece of 4 Oz. tooling leather and got it good and wet so I could form it to the shape of the grip. The wet leather is on the right. I gets much darker when you wet it.
http://i28.photobucket.com/albums/c239/212007154/josh%20bow/grip1-1.jpg
While it's wet, it can be formed and shaped and stretched to fit the contour of the riser. Once I had it shaped, I used a blow dryer to dry it off.
http://i28.photobucket.com/albums/c239/212007154/josh%20bow/grip2-1.jpg
http://i28.photobucket.com/albums/c239/212007154/josh%20bow/grip3-1.jpg
So far during this build along, I have been pretty good about taking pictures of each step. Until now. I must be getting tired because I did a bunch of stamping and tooling on the leather but forgot to get pictures of the process. After stamping and cutting the leather to it's final size, I punched some lacing holes. I then applied a coat of rubber cement to both the inside of the leather and the bow's riser.
http://i28.photobucket.com/albums/c239/212007154/josh%20bow/grip4-1.jpg
After lacing, I gave the leather a coat of Neats foot oil to restore the oils lost during the working of the leather and from blow drying. The oil makes the leather even darker. Now, you can see the tooling and stamping I forgot to take pictures of earlier.
http://i28.photobucket.com/albums/c239/212007154/josh%20bow/grip5-1.jpg
http://i28.photobucket.com/albums/c239/212007154/josh%20bow/grip6-1.jpg
Then I took it outside for a picture in natural light.

The bow project is finished with the exception of the fact that Josh wants to design and make his own broadheads. It was a fun project and I learned a lot of useful stuff for the next bow.

And finally he got to shot if for the first time.
http://i28.photobucket.com/albums/c239/212007154/josh%20bow/firstshot2.jpg
http://i28.photobucket.com/albums/c239/212007154/josh%20bow/firstshot.jpg
I then shot the bow through a chorongraph using a 125 grain field point. This brought the total arrow mass to 425 grains. The speed at 28 inches of draw was 174 FPS. This will produce 28.5 Foot pounds of K.E. giving him even more reason to keep any shots on game at less than 20 yards and broadside. This will also be a design consideration when he starts to design the broadhead. All good lessons.
Now, as for naming the bow, We thought on it for some time and kept coming back to the first post where I explained the the bow was being made with a sort of legacy piece of wood. That name stuck. I explained to Josh that this bow is only to be handed down to one of his children. I hope I am around to see that.

During the bow build, I bought a new digital camera that will also shoot video so I used Josh as my Guinea Pig. I told him to shot 3 arrows into the target. I had him stand about 5 yards away because I was burning brush in our backyard fire pit and that was where we had to stand to stay out of the smoke.
I told him to fire the 3 arrows and not to talk or look in the camera. His first shot was a dead center hit on the bullseye. The second shot cracked the nock of the first arrow and made it glance out. You can tell by the way he shakes his head that he wants to look at the camera and say something.
Here is my first ever video staring Josh and his homemade custom Longbow.
